Specification forming part of Letters Patent No. 164,711.3, dated June 22, 1875 application filed May 22, 1875. A

To all whom it may concern Be it known that I, J oHN M. KIMBALL, of Wyoming, in the county ot' Jones and State of Iowa, have invented a new and useful Improvement in Hog-Trap, ot' which the following is a speciiication:

Figure l is a front view of my improved trap. Fig. 2 is a horizontal section ot' the same, taken through the line a.' x, Fig. I.

Similar letters ot' reference indicate corresponding parts. l

The object of this invention is to furnish an improved trap for catching and holding hogs while being ringed or otherwise operated upon, and which shall be simple and inexpensive in construction, convenient in use, and effective in operation, holding the hogs securely, and without injuring their.

The invention consists' in the combination of the base, the posts, the cross-bars, the stationary board, the pivoted and slotted board, the lever and the pawl, with each other, ,to adapt them for use in catching and holding hogs, as hereinafter fully described. Y

A is the base-board ot' the trap, into which are framed the lower ends of two posts or uprights, B, the upper ends of which are connected'by a cross-bar, O. D E are two boards, of such a width that when placed parallel with each other and the posts B the spaces between them, and between them and the posts B, may be so narrow that hogs cannot get their heads through. rIhe upper end of the board D is secured to the cross-bar O, and to the cross-bar F placed upon the outside ot' the board D, to 4strengthen the connection, and to serve as a keeper. rEhe lower end of the boa-rd D is secured to and between the cross-bars G Il, which are attached to the lower ends of the posts B. The upper end of the board E is pivoted to and between the cross-bars O F. The lower end of the board E is left free, and swings in the space between the cross-bars G H as a groove. I is a double lever, the parts of which are placed upon the opposite sides of the boards D E, parallel with each other, and

their rear ends are pivoted to the upper part of the stationary board D near its outer edge. The forward parts of the lever I are connected by a pin or bolt that passes through a slot formed longitudinally in the middle part ot' the pivoted board E near its outer edge. The outer end f one ot' the parts of the lever I projects, to serve as a handle for operating it. J is a pawl, pivoted to the upper part of the pivoted board E near its inner edge, and the engaging end ot'which engages With notches formed in the upper edge ot' the outer part ot' the lever I. i

In using the trap it is secured in a gap in the fence or in the barway, gateway, or doorway ot' a yard or pen, by means ofthe hooks or staples K-attached to the outer side ot' the posts B, or by stakes driven into the ground through holes in the end parts of the base A. The outer end of the lever I is then raised to swing the lower end of .the board E outward, to open a space between the boards D E wide enough for a hog to pass his 'head through. The hog is then driven to the trap, and as he passes his head through the said space the lever I is lowered, swinging the lower end ot' the board E inward, catching the hog by the neck, and holding him securely while being' .operated upon, the pawl J taking hold ot' a ing and holding hogs, substantially as herein shown and described.
